B) Was greatly damaged by the abolition of slavery.

Explanation:

Prior to the war, the South's economy had been put together carefully with respect to farming, chiefly cotton, tobacco, and sugar, and every one of these businesses endured particularly cotton. Southern cotton generation in 1870 was half what it was in 1860.  

The training framework in the South had for all intents and purposes vanished, alongside the old manor framework. More than 250,000 of the South's young fellows were gone, as well. "Pretty much the whole of life has been merely not dying," composed the Southern writer Sidney Lanier about the Reconstruction time frame.  

Two after war changes ruled Southern life. One was the befuddling new world looked by the liberated slaves. The other was another cultivating practice, known as sharecropping, that would at last make life increasingly hard for both ex-slaves and poor whites.

polling is a process and the outcome is not involved in the process itself.

the outcome, which is an unfavorable rating for a particular candidate is not affected by the mechanical process of polling.

it rather depends on the number of people voting in favor of the candidate.

this is an outcome of people's preferences.
